I'm trying to buy a new switch for my tablesaw (old one broken), and I'm a bit confused...
NVR switches
Since removing the old switch, I have discovered that I have a spare Brown wire (that used to go to a terminal on the old switch). It's not needed to power the machine, therefore, I am guessing that it must have a role to play with regard to the switching/safety - is this something to do with the NO VOLTs bit of the NVR???
START/STOP switches
I've tried using a couple of these - one was an old MEM switch that tripped via a heat triggered mechanism (if the saw load caused the amps to get high enough to cause sufficient heat in the switch, it would trip off); however, it could not cope with the power of the saw under normal running conditions. I then bought another MEM switch which seems to be electronically controlled and I'm figuring could be a NVR switch? No idea how to wire the thing up though, particularly as it caters for single and 3 phase :shock:
If there is anything that anyone can tell me to confirm my theories above or otherwise enlighten me, I would be ever so grateful!
Cheers
